GNOR TO THE AMERICAN BALL-BEARING COM- ANTIFRIGTION-BEARING.

" My invention relates to anti-friction bearin s, more especiallyapplicable to the front ax es, and the steering mechanism thereof.

One of theprimary objects of this invention is to eliminate the outwardextension of the hub portion of the steering wheel, by so mounting thewheels in relation to the spindle, that the spindle extends inwardly,while at the same time attaining a rigid mounting and an' easily runningwheel.

Another object of mount the wheels upon their spindles, that the mainstress sustalning bearing is mounted within the line of the tread of thewheel, which hearing may be an anti-friction bearing either of the ball,roller, or analogous type; and to so mount'and locate the sustamingbearings at either end of the'spindle and hub portion, as to allow ofthe steering knuckle with its sustaining siindle to be. locatedintermediate between the two bearmgs.

Another object of this invention is to so arrange and assemble theparts, that in the main sustaining-bearings, the anti-friction members,such as balls, rollers, or analogous bearings, are mounted so. as totraverse within the journals or races, sustained mainly by. the knucklerams, which form part of the knuckle joint; and also mounting thesteadyin or anti-friction bearings, either bal s, rolers, or otheranti-friction bearings, so that they traverse within the journals orraces supported by the inner end of the spindle, thus bringing the mainstress of the weight upon, the knuckle joint, instead of upon an part ofthe spindle, and causing the spin is to act only as a means for bracingor steadying the wheel.

Other objects of this pear hereinafter the above being some of t main orprincipal objects.

This invention consists first in the mechanism and assemblage of partswhich act in Specification 0! Letters Patent. Application filed April 2,1906. Serial No. 309,387.

is ocated intermediate between the two bearings, which are adjacent theends of the spindle. Second in locating the steering knuc le between thetwo bearings, one o the wheel, and interior of the saeemg knuckle.

locating antifriction bearings and their eooperating mechanism, ballroller, or analogous bearings, one within the line of the tread of thewheel, and the other interior of the tread of the wheel, with thesteering knuckle or mechanism, wheel, said steering knuckleforming thethis invention is to so invention will apmain su port for the bearinswithin the line of t e tread of the for the anti-friction devices. andcombination of parts, all of which be hereinafter fully set forth andclaimed In thedrawing the figure illustrates an anti-friction bearingembed ing my invention, the u per portion of w 'ch isshown in section toi lustrate the internal construction and arrangement; the lower portionshowing the outer contour of the arts. is an illustration in side eevation.

It will be understood that while I have illustrated, a ty e ofanti-friction bearings which embody alls, rollers, or analogousbearings, that I do not wish to be limited to the style of the bearings,inasmuch as they may be modified, and undoubtedly will be modifiedaccording to requirementsor convenience. Heretofore and before myinvention, as illustrated in a patent granted to me Mar. 1, 1904, foranti-friction bearings N 0. 753,820,

I have illustrated and described an anti-friction bearing, in connectionwith a steering knuckle which embodies the placing of two sets ofanti-friction bearings intermediate between the spindle and the hubadjacent the ends thereo said antifriction ear'ings being of differentsizes, the lar er of said anti-friction bearings being locate in linewith the traction or tread o thewheel, and the steering knuckle which iscarried by the spindle is. in juxtaposition to the larger anti-frictionbearings. In this device however the hub portion extended outwardly fromthe wheel, and the smaller which is located Within. the tread of thewheel, and the other interior of the tread of Third this inventionconsists m also located interior of the This figure coo eration: wherebythe steering knuckle whee in GOIIlblIMr tion with the s indle whichforms the beaning portion at t e opposite end of the spindle,

This invention further consists in the parts i tending anti-frictionbearings were located at the outer end, and the steering knuckle whilelocated in juxtaposition to the larger antifriction bearings was locatedinside of both bearings and inside of the wheel. I have found howeverthat it is desirable in some cases to eliminate the outwardly extendingportion of the hub in order to allow the vehicle to pass throughnarrower openings, or along narrower thoroughfares. I have also found.that less danger arises when passing other vehicles of interference orengage- Inentof the vehicle, when the outwardly exporti'on of the hubwas eliminated; but I have found it desirable to have one of thebearings within the line of the tread of the wheel, and the other beyondthe tread of the wheel, the former to sustain the load, and the latterto support the wheel and bearings, and hence the utility and novelty ofmy invention.

Referring to the drawing, A represents a vehicle wheel the spokes and.hub portion only of which are shown in the drawing.

B represents the hub portion of the wheel, the spoke portion being heldto the hub in any suitable manner, one manner being shown in thedrawing, comprising flanges a, a. The flanges a, (4, comprising anannular disk having orifices for the reception of the securing bolt a.The space between the flanges a, a, is adapted to receive the inner endof the spoke of the wheel A. However instead of using this construction,other constructions may be used, such as wire spokes, secured in thewell known manner.

As illustrated in the drawing the inner flange a, is continuous with acup shaped recess B which may be formed by pressing, drop forging, orcasting the metal of which it is composed into shape. The portion thusfar described forms the hub proper of the wheel.

At the outer portion of the cup or hub portion B it is formed with aradially inwardly extending flange B having an orifice 'b, at itscentral portion, for the admission of the spindle, C, this spindle beingprovided with a cap or head C overlapping the orifice b, and secured tothe flange of the hub proper B, by means of a bolt, set screw, or rivet,such as 6, this forms or constitutes an attachment between the hub B ofthe wheel, and the spindle C, causing the spindle to revolve with thewheel when the wheel is in motion.

Interior of the cup or hub proper B I locate a cup race 6 which in thiscase is shown as a where such bearings are employed.

' D represents the steering knuckle formed approximately shaped havinhorizontal arms, D, D, and vertical arms D, D The vertical arms D D arepreferably cast or formed outside of the line of the spindle C, so

but which may be a roller race that the bearings E, of the same will notinterfere with the action of said spindle but will be clear of the same.

The arms D, D of the knuckle entirely support the wheel and the weight,and are formed strong enough for' this purpose.

The outer arm. D which is approximately formed cylindrical, is shown asbeing provided with an annular recess d into which fits a cone F, whichcone is supported within said annular recess (2', free of the spindle O.

Mounted upon the cone F which forms part of the race is a largeanti-friction bearing 1*" in this case shown as a ball, which inconnection with the cup race 6 forms tlie'race for the anti-frictionbearing.

It will be seen that the entire Weight is borne upon the arm D of theknuckle D.

For the purpose of eliminating dust or foreign matter from the interiorof the race, I provide an annular ring 1', against which is placed anannular ring of felt or like material f. The ring 7', is held ininterfere with the antiriction bearings,

allowing the wheel to revolve freely around the outer end of' said arm.It will be seen I in this connection that the antifriction device, be itball, roller or other anti-friction bearing is located within the lineof the tread of the wheel.

The arm I) of the knuckle is formed with a cup shaped recess G, which inturn is provided with a cup race G.

Mounted upon the spindle C at its inner end is a cone 0 which is mountedso as to be shifted lengthwise of the spindle, forming in connectionwith the nut N, a means of adjusting the bearings of both anti-frictiondevices.

Between the cone 0 and the cup race G are a series of anti-frictionbearings g, in this case shown to be balls. preferably smaller indiameter and in area than the bearings F as their function is only toact as a su. portagainst lateral strain on the wheel, and to keep thesame from irregular lateral motion, the main load being borne by theballs or rollers F located within the hub of the wheel, and in turntransmitted to the arm D of the knuckle D.

A cap K covers the end of the arm D of [the steering knuckle D, andincludes the place so as not'to end of the spindle with itsanti-friction bearing, thus excluding any dirt or foreign matter fromsaid bearings, and permitting of easy access for the or adjusting t em.

The vertical arms D D as before stated are located to one side of thevertical center of the knuckle D, and are provided with journals J atthe upper and lower end of the same. The journals J in turn are mountedin a two armed fork ll, L the journal J being secured in position at theu per end by means of a nut 7', and at the lhwer end by urpose ofremoving the parts These bearings are As hereinbel'ore stated but mayemploy any 3 means of lock nuts, f, the nut 9' being located at theupper end of the arm L, and the nut 9' being located at the lower end ofthe same, at opposite sides of the arm. The lower end of the spindle Jbeing screw threaded so as to engage both nuts, and to allow of theadjustment up and down of the knuckle D, which rests upon the nut j. Theobject of this being to adjust the ball bearing mechanism J located atthe upper end be- 3 neath the arm L.

An oil cup O communicates with a conduit 0, which supplies oil for thebearings.

Connected to the lower vertical arm D is a steering arm S which in turnis connected to the steering bar (not shown).

The forked piece L, l/ constitutes the front axle of the vehicle, and isconnected to the body of said vehicle. The operation of the steeringknuckle as far as regards the turning of the wheels for with. theexception of the location and construction of the parts, is the same asthe ordinary steering mechanism.

I do not wishto be limited to ball bearings, bearings, such as ball,roller or any other bearings and hence the details and the asscm blageof these details will be altered in the well known manner to accommodatethe parts for the reception and operation of the same, and I do not deemit necessary hence to illustrate the various kinds of bearings, and themanner of applying the same to the construction I have described, as itis within the knowledge of any ordinary mechanic skilled in the art.

\Vhat I claim is steering purposes,
